Dollar General complaint: Absolute disrespect, defamation of character, harassment

I went into yhe store with my backpack and the clerkon duty out loud from behind the register and i was at the very end of an isle , she screamed as loud as possible for me tobring my back pack up to the front of the store that it was store policy to not belting in backpacks and she proceeded to say things such as only tweekers bring back packs into stores to steal and proceeded to make more extremly rude comments to me and her coworkers outloud and i proceeded to leave. So i went back several weeks later with my roommate and i was on an isle and a dollar general employee approached me and told me i had to leave the store immediately that i had been banned from the store. When i asked her for the reason she said she didn’t know, that her general manager told her to ban me. She also stated that he had never seen me in there during the day in which he worked. I then asked her his name and she said she only knew his first name was Steve and she had no idea hos last name. So i will persue this until all of the employees loose there jobs because the level of u professionalism and disrespect and so much more is completely unacceptable.
